EYEGLASS-MOUNTIN G.

Application filed August 18, 1915.

T all whom it may concern:

Be it known that I, JonN RUTSON VAN TASSEL, a citizen of the United States, and resident of Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Eyeglass-Mountings, of which the following is a specification.

This invention relates to eyeglassmountings of the type in which the nose-clamps or guards are carried by spring-controlled levers, which are pivoted at the ends of a rigid bridge and controlledby finger-pieces at the front of the mounting.

One object of the invention is to provide, in a novel and simple manner, for the support of the springs by which the nose-clamp levers are controlled.

Another object of the invention is to provide stops to limit the swinging movements of the levers about their pivots.

A third object of the invention is to provide smooth flat bearingsurfaces for the nose-clamp levers, adjacent the pivots on which they are mounted.

To the foregoing ends I employ, in con nection with the bridge, the nose-clamp lever and the pivot by which the lever and the bridge are connected, a sheet-metal member which is interposed between the lever and the bridge, thus providing a bearing-surface for the lever, and this member is provided with an arm adaptedto serve as a support for the spring by which the lever is con trolled, or with lugs adapted to act as stops to limit the swinging movements of the lever, or with both of these features, while it is also so formed as to prevent it from turning, on the bridge, about the pivot by which it is secured in place.

In the accompanying drawings: Figure 1 is a plan-view of a part of an eyeglassmounting embodying the present invention, on a greatly enlarged scale; Fig. 2 is a rearelevation of the same part; Fig. 3 is a righthand elevation of the same part, with the bridge shown in section on the line 3-3 of Fig. 2; and Fig. 4 is a perspective view of the combined bearing, spring-supporting and stop-member in which the present invention particularly resides.

The invention is illustrated in an eyeglassmounting in which each lens 5 is fixed in the usual lens-clip 6, this clip being fixed Specification of Letters Patent.

to one end of the rigid bridge 7 in the usual manner. The bridge is perforated vertically to receive the pivot-stud 8, which is screwed or otherwise fastened in the bridge, and on this stud is mounted the nose-clamp lever 9, provided with the usual finger-piece 10 for operating it.

The nose-clamp lever does not directly engage the bridge 7, but has a bearing upon the upper surface of a sheet-metal member 11, which lies .upon the upper surface of the bridge and is perforated to receive the pivotstud 8, being thereby fixed in position on the brldge. This member 11 has a straight edge 12 which engages the lens-clip, as shown particularly in Fig. 1, so as to prevent rotation of the member on the bridge, and such ro tation is further prevented by a lug 13, bent downwardly from the member and engaging the forward surface of the bridge.

The member 11 performs several useful functions. In the first place, it provides a fiat and smooth bearing-surface for the noseclamp lever. In the manufacture of a mounting of the type in question the operations by which the bridge is shaped, perforated, and attached to the lens-clip are such as tend to leave the upper surface of the bridge more or less uneven and rough, and difficulty and expense are encountered in securing a smooth bearing-surface at this point. The member 11 being stamped from smooth sheet-metal, affords such a bearingsurface in a convenient and inexpensive manner, and avoids the necessity of great care in forming and finishing the upper surface of the bridge. In thesecond place, the member 11 serves as a convenient means for providing a support for the spring by which the nose-clamp lever is controlled. To this end an arm 14 is formed integral with the member 11, this arm being bent downwardly at the inner edge of the member, and serving as a support for the coiled part of the spring 15, this spring having ends 16 and 17 which engage, respectively, the lever and the lens-clip. To secure the spring in place on the arm 14 the lower extremity 18 of the arm is bent inwardly, as shown in Figs. 3 and l. In the third place, member 11 provides conveniently for the provision of stops to limit the swinging movements of the nose-clamp lever. For this purpose lugs 19 and 20 are bent upwardly g at the inner corners of the member 11, in

Y position to engage the edge of the noseclamp lever and limit, respectively, its outward and inward swinging movements.

I claim 1. In an eyeglass-mounting, the combination, with a bridge, a nose-clamp lever, and a stud, upon which the lever is pivoted, fixed in the bridge, of a bearing-plate interposed between the bridge and the lever and having a lug arranged to engage the lever to limit the swinging movement thereof.

2. In an eyeglass-mounting, the combination, with a bridge, a nose-clamp lever, and a stud, upon which the lever is pivoted, fixed in the bridge, ofa bearing-plate interposed 7 between the bridge and the lever and having an arm, which extends substantially parallel a stud, upon which the lever is pivoted, fixed in the bridge, of a bearing-plate interposed between the bridge and the lever and having an arm, extending substantially parallel with the pivot-stud, for the support of a coiled spring, and a lug arranged to engage the lever to limit the swinging movement thereof. 7
